In Depth Information
● The migration service then starts to migrate the contents, contacts, and calendar
items from the on-premises mailboxes to their corresponding online mailboxes.
When content migration is done, another report is emailed to administrators.
● At this point, you can create and start additional migration batches.
● When you are done with migration, change the MX records so that email will be
directly delivered to the online mailboxes. You can then complete the migration. The
migration service will carry out any necessary cleanup and checks to make sure every
MEU that has a corresponding on-premises mailbox has been migrated. A final status
report will then be sent to the administrator.
Creating a .csv file
The first order of business to carry out a staged migration is to create a .csv file containing
the attributes of mailboxes you want to migrate. The first row of the .csv file is the header
row and should contain only the following attribute names:
● EmailAddress This is the SMTP address of the mailbox and is the only required
● Password The password that will be set for the cloud-based mailbox after it is
migrated. This is an optional attribute and is not required if single sign-on (SSO) is
enabled. If you set the password in the .csv file and SSO is enabled, it will be ignored.
Simply leave this box blank if it does not apply to your configuration.
● ForceChangePassword This Boolean attribute specifies whether the user must
change the password when first logging on to the cloud mailbox. The value is either
True or False . This is also an optional attribute and is not required if SSO is enabled.
If you set this attribute in the .csv file and SSO is enabled, it will be ignored. Simply
leave this box blank if it does not apply to your configuration.
